Influenza virus. Coloured transmission electron micrograph (TEM) of an influenza virus,a cause of human influenza (flu). This virus belongs to the orthomyxovirus class of RNA (ribonucleic acid) viruses,all of which possess an affinity for mucus. The virus is surrounded by a protein coat,or capsid (pink),which is covered in specialised molecules called glycoproteins (not seen). The glycoproteins allow the virus to attach to and infect the cells lining the respiratory tract. Symptoms include a fever,a cough,a sore throat and a runny nose.
